Technik
The stucco lattice of this window is probably a cast of the latticework of window IG_362. As with the original, coloured pieces of glass were placed on the back of the openings in the stucco lattice and embedded in a thin (2–3mm) layer of stucco. In contrast to IG_362, there are no signs that the pieces of glass were fixed onto the lattice with an adhesive before embedding. The stucco panel is c.40mm thick. It is held in a wooden frame that is 43mm thick.
The coloured glass is 2mm thick; it is slightly thicker than the colourless glass (1–2mm). Some of the pieces of glass show elongated bubbles, suggesting that the glass sheets from which the pieces were cut were mouth-blown. The pieces of glass were cut roughly according to the design of the latticework using a glass-cutter. Scratch marks along the edges of several pieces of glass bear witness to this process.
Erhaltungszustand und Restaurierungen
The front of the window shows several cracks and losses in the latticework. On the back, there are some defects in the thin stucco layer and glass losses. The window shows no signs of previous restorations.
